'MACHIN E FOR. PERFO RATING PAPER PATTERNS.

SPECIFICATION forming part of Letters Pat'ent No. 398,572jdated February 26, 1889 Application filed March 5, 1888. Serial No. 266,207. (No model.)

Figure 1 is an elevation of my improved patternperforating machine attached to a table; Fig. 2, adetail of the upper end of the supporting-rod and adjustable pulley thereon; Fig. 3, a detailed longitudinal section through the perforating-needle in line a :c of Fig. 1;

v and Fig. 4', a horizontal section in line 3 y of Fig. 1, giving a plan view of the hand plate or base.

The object of my invention is to provide a firm, stable, yetreadily-movable support for a stencil-perforating needle which is geared by an elastic cord with a revolving pulley.

Itconsists in the novel devices hereinafter described and claimed, whereby the desired end is fully attained.

In the accompanying drawings, A represents the table or stand'upon which the paper or stencil-board to be perforated is placed; l3,a scrcwclamp adapted to be readily at,- tached and made fastto the edge of a stand or table; C, a stud-axle carried upon an arm or bracket projecting outwardly from the clamp; D, a crank wheel or pulley revolving upon said stud-axle; E, a treadle, and F a connecting-rod by which the trcadle is coupled to the wrist-pin G of the crank-wheel,so that the wheel may be driven by the play of the treadle.

The upper bar of the screw-clamp, which projcctsover and upon the top of the table. is formed with a socket-piece and socket, ll, at its end, adapted to receive and firmly hold a detachable rod, l, the socket bcing inclined so as to cause the rod inserted therein toproject upwardly at an inclination with the table sutlicicnt to carry its upper end inwardly from the edge to which the clamp-screw is attached, as shown in Fig. 1. To the upper end of this inclined rod is fitted a longitudinal screw, J, working through ears or side plates, K K, fixed to the rod,-whereby a longitudinal adjustment may be made of the screw upon the rod, it being fixed when adjusted by means of lock-nuts L L, working upon the screw against opposite sides of one of the ears K, as shown in Fig. 2. The outer end of the screw J terminates in a yoke, J, ati'ording pivotal bearings for the ends of a transverse axial shaft or spindle carrying two grooved pulleys, M N, of different diameters. The pulleyN is geared by a cord, 0, with the crank wheel or pulley D,the tension of the cord being regulated by the longitudinal adjustment of the screw J.

Prepresents the reciprocatingneedle bar or rod, havinga socket in its lower end, in which the perforating-needle P' is secured in the customary manner by means of a set-screw, 1', or other'devioe. This needle-bar is made to reciprocate freely in a standard, Q, upheld in a vertical position at a right angle to the face of the tableA, upon which the work is placed by means of a bracket-bar, R, projecting atan angle from a flat base-plate 0r hand-plate, S, adapted to rest firmly upon and move freely over the table, and which is preferably made wide enough to allow the fingers or some portion of the hand of a person holding the standard to rest or bear thereon and hold it. down in place upon the table. The upper end of the standard Q terminates in a yoke, T,

affording bearings for the end of atransveise shaft, 1', formed with a crank, U, to which the upper-end of the needle-bar islcoupled, and carrying a pulley, \V, which is geared to the pulley M at the outer end of the inclined rod I by means of an elastic cord, Y, which permits the needle to be freely moved to and fro over the table in all directions within a limited radius under the pulley N,whilc'in constant gear therewith.

When the needle is not in use, it may be hung up, as illustratmlby dotted linesin Fig. 1, upon a hook, X, attached forthe purposeto the rod I.

In the use and opt-ration of the needle the driving whccl or pulley I) is attached by means of the clamp-screw B to the table A, uponwhieh the work is to be placed, and the treadle E is connected thereto. The rod I is forations, the constant connection of the crank 25 then inserted and secured in its socket H and operating the needle with the driving-Wheel the cord 0 led orerthe pulleys D and N, and operated by said treadle being maintained as Thestencil-paper to he perforated l l l 1 is laid'upon the table A under the end of the Y of a pattern of any description.

l i l needle at a right angle to the surface of the i paper to he perforated.

While the needle is the needleis made to traverse the paper ,by means of the elasticity of the cord or belt Y.

I claim as my invention and desire to secure by Letters Patent- I The combination, with a reciprocating stencil-perforating needle and the case inclosing the same, of the fiat extended base-plate and the interposed bracket-bar connecting the plate and case, whereby the needle is upheld in a vertical position by the base-plate independently of other support, substantially in the manner and for the purpose herein set; forth.

In testi mony whereof I have signed my name to this specification in the presence oftwo sub scribing witnesses 3t. BENDICK.
